Abstract
Sequence learning plays a central role in motor skill acquisition. One of the algorithms that is essential to the consolidation process is binding, where multiple movements are driven by a single motor command. Here we show that this binding process originates from learning the transitional probabilities between sequential movements. To determine how binding impacted the neural population patterns which control the movements, we generated unbiased encoding networks of the movement representations at multiple levels of the motor hierarchy. The representational geometries associated with individual movements and movement sets were readily dissociable. In addition, the set network comprised a subset of the individual movement network. However, extensive training by human participants on a sequence learning task did not result in any shift of the representational geometries. This suggests that the representations associated with expert performance are rapidly constructed and highly stable.
